"Click here" box

I am sure this is really easy and I just can't see the
forest for the trees. On my title slide I want a "Click
here" box that automatically deletes that text and then
let's you start typing your text there. THe basic thing
I am after is for an instructor to see a box that
says "Your name here" and when he clicks in that text
box, that text is deleted and he's sitting there with
the "I" bar already justified in the center of it and
ready for him/her to type their name in for the
presentation.

Any help would be greatly appreciated ! I have searched
and have not hit the right combination of words to turn
this answer up. I thought a placeholder was what I was
looking for, but I can't create those according to what I
found.

TIA
